SAN DIEGO — Game of Thrones fans haven't seen the last of the Martells.

Relatives of the late Oberyn Martell (Pedro Pascal), who was killed late last season, are among nine new arrivals to Westeros and its surroundings for next year's Season 5 of HBO's top-rated series. The cast additions, replenishing the ranks after last season's bloodbaths, were revealed during a Thrones session Friday at Comic-Con International: San Diego.

New cast members and their characters, as described by HBO, include:

• Alexander Siddig as Doran Martell, the ruling lord of Dorne, which is located in the southern part of Westeros, and the older brother of Prince Oberyn. Unlike his brother, Doran is even-tempered and deliberate, and Dorne residents will want to see how he reacts to his brother's death.

• Toby Sebastian as Trystane Martell, Prince Doran's son and heir to Dorne. He was betrothed to Myrcella Baratheon as part of the alliance offered by Tywin Lannister (Charles Dance), who was killed by his son, Tyrion (Peter Dinklage), in the season finale.

• Nell Tiger Free as Myrcella Baratheon. She is officially the eldest child of Cersei Lannister (Lena Headey) and the late King Robert Baratheon, but her real father is Cersei's brother, Jaime Lannister (NIkolaj Coster-Waldau). For years, she has been a guest and ward of Prince Doran in Dorne, but her position has become tenuous with the death of Oberyn Martell, the Prince's brother.

• DeObia Oparei as Areo Hotah, the long-serving captain of Doran Martell's palace guard. He is renowned for his loyalty and his long axe.

• Jessica Henwick as Nymeria ("Nym") Sand, who is the second eldest of Oberyn's bastard daughters. Her mother was an Eastern noblewoman who brought Nym up to be cultured, graceful and deadly with a whip.

• Rosabell Laurenti Sellers as Tyene Sand, who is the daughter of the late Oberyn Martell by Ellaria Sand, his final paramour. Tyene is fiercer than she looks, especially with her twin daggers.

• Keisha Castle-Hughes as Obara Sand, who is a fearsome warrior and the eldest bastard daughter of Oberyn Martell. Her mother was a Dornish peasant girl who caught the eye of the late Prince.

• And Jonathan Pryce as the High Sparrow, a devout and pious man who came to King's Landing to serve those forgotten by much of the world — the poor, the downtrodden and the infirm — and quickly amassed a large following.
